The invention relates to an anti-drowning inflatable lifesaving device, and in particular relates to an anti-drowning airbag inflatable lifesaving device used in emergency during swimming. The deviceis characterized in that a gas generator adopts a sealing bag flexible package design, an external water source is sucked into the device by virtue of expansion of compressed sponge, and a dissolved gas generating agent reacts to generate gas, so that the device is small in size, light in weight, convenient to use, safe and reliable. The device comprises a sealing bag, elastic sponge in the sealing bag, the water-soluble gas generating agent, a water inlet formed in the sealing bag, an anti-backflow membrane in the water inlet, a water inlet sealing cover, a pull ring on the sealing cover, anexhaust pipe mounted on the upper row of sealing bag, an open pore in the exhaust pipe, a rubber pipe sleeved outside the open pore and an air bag communicated with the exhaust pipe.
一种防溺水充气救生装置,特别是用于游泳时紧急情况下的防溺水的气囊充气救生装置。其特点是气体发生器采用密封袋软包装设计,依靠压缩海绵的膨胀吸入外部的水源进入装置内部,溶解气体发生剂产生反应生成气体的工作方式,因此体积小、重量轻、使用方便、安全可靠。该装置包括密封袋和袋内的弹力海绵、水溶性气体发生剂、安装在密封袋上的进水口、进水口内的防返流膜片、进水口封口盖、封口盖上的拉环、安装在上排密封袋上的排气管、排气管上的开孔、开孔外套的橡胶管和接通排气管的气囊。
